基于新材料的梁抗弯性能实验教学探索

以聚丙烯纤维增强混凝土梁(PP-ECC梁)抗弯性能科研课题为依托,结合建筑材料中混凝土梁实验教学,分析了RC梁及PP-ECC梁在裂缝形态、宽度、变形情况及其承载力等方面的性能差异,对采用新型材料开展梁结构抗弯实验的新方法和新思路进行了总结,提出了将科研课题、工程实践与实验融为一体的梁式结构实验教学模式创新改革。该模式作为传统教学的优化和补充,可为其他课程实验教学革新提供思路,有利于激发学生的实验兴趣,培养其使用软件处理实验数据并分析实验结果的科研能力,以及理论与工程应用相结合的综合能力。

Exploration on the teaching of bending resistance experiment of beam based on new materials

Based on the research project, taking the bending resistance of PP-ECC beam as an example, and combined with the experimental teaching of concrete beams in building materials, this paper analyzes the differences of RC beam and PP-ECC beam in crack shape, width, deformation development and bearing capacity, and summarizes and explores the new methods and new ideas of bending experiment of beam structure with new materials. The innovation and reform of beam structure experiment teaching mode, which integrates scientific research, engineering practice and experiment, is put forward. The exploration of this new mode is the optimization and supplement of traditional teaching, which can provide ideas for the innovation of experimental teaching in other courses, and is conducive to stimulating the students'' interest in experiments, cultivating their ability of using software to process experimental data and analyze experimental results, as well as the comprehensive ability of combining theory with engineering application.
